of Tanks Blitz was released on Steam. Console versions World of Tanks: Xbox 360 Edition was developed with Wargaming West, formerly Day 1 Studios until purchased early in 2013. Day 1 was looking for a publisher for their console mech game when Wargaming asked the studio about porting World of Tanks. Day 1 prototyped the game on the Xbox 360 "in mere days". They were given unrestricted access to Wargaming's servers and art. The game's client side runs on Wargaming's Despair engine. The company aimed to give each tank class 100 hours of unlockable content, or 400 to 500 hours overall. The version is free-to-play for Xbox Live Gold subscribers, and includes a 7-day trial for Xbox Live Silver subscribers. Playing the game earns experience for tanks and accessories, and silver for buying tanks and equipment. Players can use gold, an in-game currency, to buy premium World of Tanks accounts, which in turn give players more experience and credits faster. Players can buy gold with real money in the later patches. Gold for premium accounts and tanks is the fastest method for progressing through the game. The Xbox 360 Edition is not connected with the PC game, with a separate user base and no crossplay. A closed beta test began in early 2013, and E3 2013 attendees were invited to the beta after the game's announcement. The game was working on retail Xbox 360s by mid-May 2013.

An open beta with 40 American and German tanks was scheduled to begin the weekend after E3 2013. The beta was for stress testing the servers and multiplayer matchmaking. Players could not buy gold in the open beta, but Wargaming provided free in-game gold to test the store, though this reset with the official release. British tanks were also available within the beta. About 60 total tanks were expected to be included in the full version. The open beta was released on 7 August 2013.
